By Partha Sinha Entropy fascinates because it announces itself. It spreads, decays and disperses. It makes noise. Like Kali, ...

Entropy, introduced by Rudolf Clausius in 1865, is a way to quantify the amount of energy dispersion within a system. It reflects how energy, whether thermal or chemical, becomes more scattered ...

Over the past decades, researchers have made significant progress in cooling objects closer to absolute zero, the temperature at which all molecular motion reaches its minimum. This has allowed them ...

Though a cornerstone of thermodynamics, entropy remains one of the most vexing concepts to teach budding physicists in the classroom. Physics teachers designed a hand-held model to demonstrate the ...
